Research proves that most lung cancers are related to smoking, and about 85% of lung cancer patients are or have been smokers. Of course, there are also some lung cancer patients who do not smoke themselves but still suffer from lung cancer, and the reasons are related to passive smoking, and there is also the genetic susceptibility of patients themselves, whose lung cells are more sensitive to external stimuli and more prone to genetic changes, and another is the existence of other carcinogenic factors in the environment, such as radioactive exposure factors, the presence of asbestos in the working environment, mining or interior decoration materials containing radon and automobile exhaust, etc. Yao Li, Department of Integrated Chinese and Western Medicine, Agricultural Third Division Hospital, Kashgar, Xinjiang
So the best way to prevent lung cancer is: quit smoking or never start smoking!
